Question

The complexes [Co (NH3 )6] [Cr (CN )6 ] and [Cr (NH3 )6 ] [Co (CN)3 ] are the examples of which type of isomerism ?

Options

A.Ionisation isomerism
B.Co-ordination isomerism
C.Geometrical isomerism
D.Linkage isomerism

Solution

The complexes [Co (NH3)6] [Cr (CN )6] and [Cr (NH3 )6] [Co (CN)6 ] are the examples of Co-ordination isomerism. This isomerism occurs only in those complexes in which both cation and anion are complex. It occurs due to exchange of ligands between cation and anion.
